Buxton Heath guided walk, 27 May 2021

A dry day, which was a relief after this cold and wet day, even if the sun didn’t come out, and the five of us were rewarded immediately by a singing willow warbler in the trees by the car park. Moving up the hill along Buxton Heath’s western edge, we were soon enjoying the sights and sounds of yellowhammer and stonechats. 

Stonechat, male.

We looked at currant galls and oak apples on oak trees. There wasn’t much in the way of flowers apart from gorse, though we did note four-petalled tormentil and some thyme-leaved speedwell. Farther on there was a fine lousewort in flower by the side of the path, and the first bloom of bell heather.

Lousewort.

By now a cuckoo was calling and we saw it fly past on about three occasions. We completed a loop through the wood at the north-west corner of the heath, encountering the site’s managers, namely Dartmoor ponies and British white cattle as we returned to the heath. We had good view of two buzzards, nowadays quite a routine sighting. The penny dropped that thin shrubs near the lousewort were alder buckthorns.

Yellowhammer.

Returning to the first area with the most birds, we had more view of yellowhammers, linnets and especially some rather confiding stonechats, allowing me take some digiscoped photos. A stock dove flew through and landed in a distant tree.

Ranworth revisited, 10 May 2021

Fine weather and quite a lot of sunshine: big positives to start with compared with the previous group visit on 30 April that was cut short by a fierce hailstorm.

We followed the same route, the quiet road alongside the Bure Marshes National Nature Reserve, this time with puddles showing the volume of the rain that, happily, had fallen during the night. We took a careful look at a pair of pied wagtails on a pasture on the high land to our right, taking in the blacker back and bigger bib on the male, realising how often we see them as little more than a silhouette on a roof.

View over Bure Marshes NNR.

Over the low-lying marshes, four lapwings were displaying, calling, twisting, turning and diving in flight. They then injected additional pace and urgency as they dive-bombed a crow on the ground,
then went up to mob a marsh harrier. This was one of two male marsh harriers in the sky and a scan revealed at least two more harriers over the far reedbed, plus lots of swifts. Inevitably there were many herons and Sue was alert to a little egret that flew in. A pair of gadwalls was close by on the nearest open water and others were in flight; other wildfowl were mostly greylags. Swallows and house martins were on the wing at various times during the morning.

On the paths by the meadows and the wood that backs onto South Walsham Broad we put names –sometimes multiple names, like Queen Anne’s lace and cow parsley – to many flowers and plants. Ann was on the look-out for bees, as ever; a particularly large red-tailed bumblebee comes to mind. Julie then joined the group, having cycled from Norwich.

Back at the staithe we had a relaxed cup of coffee, some with cake, from the Granary. I then picked up my telescope before we walked to the boardwalk that goes out through wet carr woodland and fen to Norfolk Wildlife Trust’s floating visitor centre on the edge of Ranworth Broad. Warblers were singing, a good range that included sedge, reed and Cetti’s warblers, chiffchaffs and a willow warbler in view on an open tree. A male reed bunting showed well, too.

Boardwalk to Ranworth Broad.

We failed to find orange tip eggs on lady’s smock flowers; the other flowers very much in evidence, in the cut fen near the visitor centre, were marsh marigolds. Lots of marsh fern was in its early stages and discussion turned to the royal fern that is known to be here, though it wasn’t until we were walking back that Ann found it. 

Royal fern, early growth.

At Ranworth Broad, the most obvious birds were black-headed gulls settled on the platform. Common terns were in good numbers, one or two on posts, but none had yet settled to nest. Great crested grebes were there in good numbers, including a pair nest-building on the floating barrier in the water put in as part of the Tipping the Balance project to restore clear water and the aquatic plants once common in the Broads.

An odd place for grebes to nest.

Helen suggested a nice detour on the return, so we turned right then across a field to the back of Ranworth Church. In the churchyard there were clumps of meadow saxifrage growing among bulbous buttercups. The path down the hill took us past alpacas to Ranworth Staithe. Some in the group went home for a late lunch and the rest of us enjoyed our picnics on benches overlooking Malthouse Broad.

Ann and I returned to Ranworth Church, partly to take a photograph of the meadow saxifrage but also to search for the recently discovered Dusted Wall Yellow Lichen Calaplaca ruderum described in the book Norfolk’s Wonderful 150. Peter Lambley, lichen recorder and author of the account of the five lichens in the book, says the “photo looks like it”, viewed on a smartphone, to be confirmed later.

Kelling Heath and water meadows: guided walk, 5 May 2021

No sooner had we set off from the Holgate Hill car park, an impressive minotaur beetle had cameras clicking as it clambered on one group member’s sleeve. A favourite food for stone-curlews in the Brecks, said our guide Rob Lucking.

Minotaur beetle Typhaeus typhoeus, a type of dung beetle.

Shortly after crossing the railway – later we enjoyed seeing one of North Norfolk Railway’s steam trains – we were lucky to have extended views of a Dartford warbler, in and around low clumps of gorse. The Dartford warbler continued to show well, if briefly, having crossed to the other side of the path. With it were not the expected stonechats but instead linnets, which seemed to be plentiful here and later by the coast.

We did a circuit of this part of the heath, telling stories of nightjars watched here while staying on the adjacent camping and caravan park. The route includes a fine view down to Weybourne church: what looked like crenellations on the church are part of the remains of a 13th century priory.

Lots of coconut-scented gorse in flower at Kelling Heath.

We re-crossed the railway line and on the edge of the footpath near the firebreak were heath milkwort flowers in both blue and dark pink.

Heath milkwort.

We drove closer to the coast to Kelling Reading Rooms, an appealing & eccentric mix of second-hand shop and café, for coffee and loos. Those with the group for the afternoon session had their picnics in their cars, parked by the roadside stream.

Over the coast road we walked along the alexanders-fringed path. Hearing a cuckoo was the highlight here, plus glimpses of another flying away – a russet-plumaged female. We continued to hear the male and get distant views of the female through the afternoon.

There was a white wagtail by the cattle inland of the biggest lagoon. That water body had avocets, shelducks and gadwalls. But the star bird was on the short grass on the seaward side: a whimbrel, feeding briskly, taking short flights and calling from time to time, but often still enough for outstanding views.

Whimbrel.

We clambered the shingle ridge and looked out to sea, though the best bird was behind us: a wheatear. We followed the path to complete a circuit alongside the WW2 sea defences showcased at the Muckleburgh Military Collection. 

A stonechat, lots of linnets and a soaring skylark were among the birds here, and a small hawthorn had a cluster of brown-tail moth caterpillars.

Rain Stopped Play: Ranworth guided walk, 30 April 2021

Reports about Honeyguide guided walks are partly a souvenir for those there, plus we hope the usual account of lovely wildlife sightings to encourage others to wish they were there.

But not today, I think. Using the long-range weather forecast to help choose dates is better than not looking at the forecast, and perhaps it’s best to appreciate how often it’s right.

We started well, it has to be said. Chilly, certainly, this exceptionally cold April, and when the sun came out on a couple of brief occasions, very pleasant. The group walked from the NWT’s car park along the quiet road alongside the Bure National Nature Reserve. On a meadow on the higher land to our right there were four hares.

To our left, muddy areas among rushes and reeds showed the impact of some serious flooding last winter, creating good habitat for displaying lapwings. A pair of Egyptian geese emerged from tall rushes with chicks that were so patterned and fluffy it was tricky to tell where one stopped and the next started; we think there were about eight of them. Greylags were plentiful, gadwalls and herons flew over and we had a good view of a male marsh harrier over the reeds. Sedge, reed and Cetti’s warblers were singing at various points.

Ground ivy.

Roadside verges were coming into flower, with patches of ground ivy, red dead-nettle and germander speedwell, on which we looked at the parallel lines of hairs on the stem. Two comfrey species, soft (aka white, oriental or Turkish comfrey) and tuberous comfrey were side by side, garden escapes that have become wild flowers.

Soft comfrey, left, tuberous comfrey, right.

Turning right, a hare ran down the grassy track towards Ann and me until it veered off when it saw us. There was another in the field, with red-legged partridges and lots of woodpigeons.

As we walked along the back of South Walsham Broad, that grey cloud looked more and more threatening. Then lumps of ice started to fall, something between frozen sleet and soft hail. We tried sheltering firstly under ivy then under holly in the hope it would blow over.

It became apparent that it was more than a passing April shower and it was wiser and warmer to keep walking, so we headed back to Ranworth and the car park. We were just agreeing to come again another day when my wife Julie joined us having cycled from Norwich, taking shelter in the old church at Panxworth on route. We returned to retrieve the locked-up bike during the afternoon.

Hail. Oh dear.

Thorpe Marshes guided walk, 26 April 2021

This was an extra guided walk to mark my birthday, and what better way to spend the morning than with a group of Honeyguiders on my local patch? A lazy option for me, as NWT’s Thorpe Marshes nature reserve is within easy walking distance, though still only occasionally visited by most of today’s group. A whitethroat on a dead branch in the field by Whitlingham Lane, the approach to the reserve, was a good start.

It was one of the chillier days this cold and dry April, but that didn’t stop the activity approaching the peak time for bird song. Right by the railway bridge that is the reserve’s entrance was a willow warbler and a Cetti’s warbler that was clearly on view: so often they are noisy yet hidden. A sedge warbler sang noisily from a buddleia that hadn’t been pollarded.

We spent a little time at the first corner looking at the egg-laying scars of willow emerald damselflies on thin willow branches over the open water. Then a little farther along the permissive path through the ungrazed marsh we stopped by a nice clump of lady’s smock. On this we looked at two tiny eggs stuck under flower buds: from orange tip butterflies on a favoured larval food plant. See if you can see one in the photo below.

Lady's smock, and hunt the orange tip egg.

Reed buntings and more sedge warblers kept us company, and there was a surprise in the eastern part of the open area of the marsh: two stonechats, a male and a female. These are a regular winter feature of Thorpe Marshes, as on other Broadland marshes, but to be still here in late April remains a puzzle. Somewhere in the big sedge beds a grasshopper warbler reeled, but only briefly and not everyone could hear it. Blackcap and chiffchaff in the wooded corner took us to seven warbler species seen or heard.

St Andrews Broad, the gravel pit, still had winter birds, namely tufted ducks and 110 black-headed gulls, though no longer a little gull – a remarkable 24 days with one or more of these unusual and charming birds here had ended on Saturday, two days ago. Common terns buzzed around, with five coming past. Swallows and house martins were nice then another surprise: a group of 15 of high-flying swifts. For a bird that we expect at the end of the first week of May it was quite something, though the Yare Valley is an area where early arrivals often appear in late April.

Heading back along the bank of the River Yare, we paused to try to get a better view of a kingfisher perching by the opposite bank. That was the female, then the male arrived. Then they mated and straight away he took several quick dives into the water: like a quick shower, it was suggested, or perhaps a celebratory plunge.

Kingfisher. The digiscoped photo doesn't do it justice, though no doubting the ID.

Compared with mating kingfishers the various botanical observations on the home leg seem rather humdrum, though the yellow blisters peculiar to the leaves of alexanders are worth noting, galls caused by a rust fungus Puccinia smyrnii.

Then there was coffee, lunch in the garden and birthday cake, courtesy of Ann. And over-flying buzzards, much closer than one in the distance this morning.

The walk raised £100 that was donated to Norfolk Wildlife Trust.

Foxley Wood guided walk, 23 April 2021

It was a perfect spring day at Norfolk Wildlife Trust’s Foxley Wood nature reserve, timed to enjoy spring woodland flowers at around their best. Even around the car park we found lots of common dog violets. A dog’s mercury we looked at had distortion and swelling on a leaf, likely to be caused by a rust fungus Melampsora populnea.

Foxley Wood in the sunshine.

Just around the corner, a willow warbler sang in full view. It’s an ideal time to see a willow warbler: freshly arrived, keen to sing to establish territory and easy to see before leaves emerge on trees. Other warblers singing this morning were chiffchaffs and blackcaps. It wasn’t a day for seeing a lot of birds though we did have good views of two marsh tits and heard mistle thrush.

Common dog violets.

 

Wood sorrel.

Mostly this was a morning for enjoying glorious weather and spring flowers. Water avens was beginning to bloom in damp patches on the wide rides. Wood anemones and wood sorrel were expected but lovely anyway. Bluebells were in bud or just coming into flower, in great carpets once we’d reached the coppiced area, just after we’d bumped into an NWT team taking a break from working on the electric fence that protects coppice from browsing deer. Bugle in bid, patches of greater stitchwort and endless lesser celandine added variety.

Wood anemones.

Brimstones, orange tips and peacocks were all much in evidence. A beetle on the path was an invertebrate curiosity: this was later named as red-breasted carrion beetle Oiceoptoma thoracicum. According to Brock’s book, adults and larvae of this species feed on other insects in dung and carrion.

Red-breasted carrion beetle.

A moth with an obviously orange underwing was later named as, er, orange underwing Archiearis parthenias. Day-flying and strongly tied to the presence of birches: sometimes going up the learning curve is easier than other times! In grassy areas, there were plenty of bees, especially red-tailed and buff-tailed bumblebees.

Foxley Wood is a great place for fungi enthusiasts in autumn. Not so in spring, though today we found hoof (or tinder) fungus on birch. This was the species found on Otsi the Iceman, presumably for its tinder qualities. James Emerson tells me that, “It was present in Norfolk before the last ice age, but has recolonised in the past 10-15 years, starting in the west in places like Dersingham.”

Hoof or tinder fungus.

We failed to find herb paris though that was more than compensated for by Cheryl being alert to an early purple orchid coming into flower. I don’t recall seeing one in flower in April, in the UK.

Burnham Norton and Holkham NNR guided walk, 16 April 2021

Sunshine with a cool northerly breeze greeted this week’s Honeyguide group, with Rob Lucking, around the grazing marshes of Burnham Norton at the western end of Holkham National Nature Reserve (NNR).

Grazing marshes at Burnham Norton.

A great white egret was out on the marshes, though it was displaying waders that stole the show. Calling redshanks rose and twisted on angled wings; lapwings tumbled and others could be picked out on the ground sitting on nests. There were oystercatchers, too, and a few curlews.

Paul Eele, warden of the NNR and a former RSPB colleague for Rob and me, came past and paused for a chat. He confirmed that the water channels on the grazing marsh had been enhanced by a rotary digger, here in the natural-looking shapes of creeks of the saltmarsh that it once was, centuries ago. In what is becoming a very dry April, Paul also told us that this old grazing marsh was retaining its water much better than marshes that are more recent reversions from arable to grass.

It was a good morning for mammals. At the back of the group, Helen and others saw a weasel cross the path. There was hare to our right and a Chinese water deer scampered across the marshes to our left before disappearing into reeds. Later, Ann saw an otter on the gravel by a gate in the marshes; two others managed to see it before it went out of sight into a ditch.

We heard a sedge warbler but we failed to find the yellow wagtail that Rob saw briefly. Later we found a singing sedge warbler that stayed where it was to allow good views through telescopes. Marsh harriers were constantly on the move. Then two more very good birds: the first was a bittern that boomed, albeit not often. The second was an immature little gull that was flying over a flooded area among a much larger group of black-headed gulls. We found it again on the return leg of our walk, including settled on the water. The dark lines on the upper wing means it was a first-winter bird, and it lacked the smoky underwing of the long-staying adult little gull at my local patch of NWT Thorpe Marshes (photos from Thorpe here).

At the farthest point of this fairly gentle circuit we overlooked saltmarsh out towards Scolt Head and inland towards Brancaster Overy Staithe. Avocets were feeding in creeks and a flock of brent geese flew towards us and settled.

View over saltmarsh towards Scolt Head.

The sea walls were dominated by alexanders coming into flower, on which were many ladybirds. There were mason bees in the dry path and one I photographed on alexanders I think was grey-patched mining bee Andrena nitida.

Grey-patched mining bee (provisional ID).

On the lagoons on this part of the walk we added shovelers, teals and tufted ducks to the gadwalls and shelducks seen already. Little egrets go almost without comment nowadays and the great white egret returned.

We said farewell to Honeyguiders not staying on for the afternoon; those out for the day had their picnic lunches in the sunshine by the cars, under the willows with the singing chiffchaff. Swallows came over us here.

A short drive took us to Lady Anne’s Drive at Holkham which was busy with people, as were the machines issuing tickets for parking. The popularity of Holkham beach means birds are acclimatised to people and the sculpted channels and scrapes in the marshes either side of the road had plenty of birds, offering close views. These include more displaying redshanks and lapwings, a snipe, close curlews, some late wigeons and more brent geese. After visiting loos at The Lookout café, we walked along the back of the pines and immediately lost the crowds who were obviously here for the beach.

It was sheltered and warm and that brought out butterflies, three that were first-of-the-year for most of us. A male orange tip flew past, then a green-veined white settled on a flowering currant. The third was a speckled wood, dancing around a stump. Peacock butterflies dashed past as well and a willow warbler sang. A marsh harrier called; the male was high above us, over the Corsican pines, in courtside display.

Holm oak leaves: the bumps are Aceria ilicis mite galls, the brown patches are leaf miners. 

We noted how holm leaves were scarred with the tunnels of leaf miners. Then Rob showed us an odd tree planted here long ago: winged elm, also called cork-winged elm on this Holkham blog; the photo shows why it is so named. Wahoo is another name given on Wikipedia for Ulmus alata, introduced from North America.

Winged elm.

Some turned back before we reached the far (and closed) hide that overlooks the cormorant colony and heronry. The others didn’t miss much: two spoonbills in flight only and no egrets on view, just cormorants and woodpigeons. We paused on the return walk to see what we’d earlier noticed a Naturetrek group observing: the larval pits of antlions, a relatively recent colonist here. The slippery sides of the pits, for trapping and consuming ants, recalled the sarlacc in the Star Wars film Return of the Jedi.

Antlion larval pit.

We all returned to the cars at much the same time and were able to enjoy a good view of a red kite over the marshes. How amazing that red kite, marsh harrier and buzzard should all be routine sightings – a transformation within our lifetimes.

We then drove a little farther west for a brief visit to North Point wetlands at Wells-next-the-Sea (previously visited by Honeyguide on a much chillier 1 April). There were many hares on the fields and waders on the lagoons, including black-tailed godwits and ruffs, but we couldn’t find the reported grey phalarope. A spoonbill and a red kite flew over.
